I am using WinRunner for some tests that have calendar objects in it, which I think are responsible for the trouble...

The fact is that the application in test goes into GPF's errors, disappear suddenly, and other kind of strange errors, and WinRunner/Test Director continue ok. I am sure that there is no logical problems or erros at WR scripts.

In fact, it is like some memory conflict is happening... Executing manually the tests, the errors do not occur.

Somebody could give me some clue of what could be realy happening or some suggestion to get out of this trap?

Thanks in advance!
